The invention relates to improvements in weeding attachments particularly deslgned for use on ploughs and an object of the mvention is to provide a weeding attachment which can be readily incorporated as part of the plough structure and which embodies a driven rotary pronged weeder mounted on the plough frame and adapted when the plough is in use to strike the earth turned by the mould board and separate the weeds from the same and pitch them rearwardly to be subsequently killed by exposure to sun and weather.

A further object is to associatedeflecting forks with the plough frame adapted to catch and deflect the extracted weeds and discharge the same on the soil surface and further to provide a shield for the rotary weeder to protect the plough operator,

A further object is to construct the attachment so that it can be readily mounted on the existing type of plough withoutrequiring any material alteration in the structure thereof.

A further object is to arrange the prongs so that they can be adjusted in length and also to provide an arrangement whereby if an obstruction be encountered, the rotary weeder will not be seriously damaged.

With the above more important and other minor objects in view, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accom- 'panyingdrawing, in which Fig. 1 is a plan view of equipped with my invention, certain parts of the plough being omitted.

well known conventional type and I. have not considered it necessary on such account invention, I remove the landwheel, the shaft 7 not further described. a sulky plough L a chain 15 which operates 'over a considers ably smaller chain wheel} 16 secured to I the counter shaft; i I The sulky plough herein'shown is" of the v v shaft is driven, at a considerably higher togive a detailed description of all the parts shown norto 'show all the parts of the sulky plough. v j The'frame 1 of the plough is substantially rectangular and it is supported as is usual'at one of the front corners by the front furrow Wheel 2 and it is also-rearwardly' supported in the usual manner by-the rear furrow wheel 3. o Thef'iplough beam 4 which is carried in the usual'manner by the plough frame is sup-- plied with a plough proper 5 embodying the customary share 6, mould board 7' and vland side (not herein shown).' The forward end of the plough beam is provided with theconventional hitch 8. Gustomarily, the plough frame is provided moreor'less centrally at the side remote from'the front furrow wheelwith what is known as a land wheel. According to my supportingthe same and other elements associated therewith and provide the plough frame at that side'with an extension frame 9 in which I mount abull or master wheel 10, the master wheel being carried by a drive shaft 11. This drive shaft is adjustably mounted in respect to the frame'sothatth'e frame can be raised or lowered in respect. to

the ground as desired. The adjustment which, I provide for the latter shaft is the same as that nowused on harvestin machines or binders now marketed an embodies the well knownsegments, gear wheels, worm and worm shaft herein indicated but Rearwardly the plough frame and the eX- tension frame are provided with suitable bearings12 for a counter shaft 13 and the counter shaft projects beyond the side of the plough frame remote from the extension frame. Suitable means is provided whereb "the shaft- 11 drives th o t Shaft; Sue

being herein shown asa chain wheel 14 secured to the main shaft and providedjw'ith 295 speed than the main shaft:

'To the end of the counter shaft extending beyond the plough frame, I secure a rotary pronged weeder-indicated generally by the reference numeral 17 and in the present instance, the weeder-is made as follows. To the counter shaft, I secure in any suitable manner a pair of opposing spaced discs and slot 21 receives a wooden pin24: also carried by the discs.

gy providingthe wooden pins which will be preferably of hard wood, I contemplate that I an ob'struction is met, the wooden pins will be sheared so that nothing will be seriously damaged as it is an easy matter to substitute a new wooden pin for the sheared one;

.1 It will be observed that the rotary pr onged v weeder is located to the rear and to the side of theplough 5 and Iconsider it desirable to have. the rear end of the mould board terininated in a vertical plane lyingimmediatevly to theinner side of the rotary weeder. In practice, the existing mould board can be used by cutting off therear end ofthemoul'd drawing. s I

the sulkyplough is in use, thebull board-so th at .it will appear as shown in the wheel will drive the rotary weeder at a fairly high speedand in the direction of theapplied arrow Eigure2 and the rotary weeder is located in respect to the mould board that the ,prongs thereof will strike the ploughed earth deflected by-the mouldboard and l-oosenthe weeds and weed roots therefrom and pitch thesame rearward.

In order-to keep the weeds clear vof the rear cfurrowwheel, I have attached the forward end of avertically disposed guard plate 25 to the rear end of the mould board andthis plate extends rearwardly far enough to positively prevent weeds from reaching the; said fiI I'IOW wheel. 7

""I have -considered it desirable to provide a shield 26 for the rotary weeder in order to protect the plough operator. This shield is secured permanently to the plough frame and presents a verticaliplate 27' which carries an outstanding guard ange 28 overlying'theuplper. half of the weeder. The plate 27, eiiten dow rd y owar the r n a h wn and'to the rear edgeef it,: I secure a of horizontally disposed equi-spaced similar, deflecting forks 29 inclined rearwardly and the "round,

W ile I have entered into a detailed description of the various parts of the invensame can materially modified without departingfromtl'ie spirit of the invention as set forth in the appended claims and further "it will 'be 'understood that'whi'le'I have des be th inye t en a a p e n s y plough, it may be used on other types: of

Themeans used for driving the rotary weeder may of course Var depending on the type of plough used and might point out 'that'if the plough is to be drawn by a: tractor having a power tak'e'ofi', suitablev driving elements can be readily mounted on the plough utilized as a'drj ing connection betweenthe pew'er take olf and therotary' weeder. a
